The Homer Simpson model consists of 10 parts (head, torso, left-arm, right-arm, left-hand, right-hand, hips/legs, left-leg, right-leg, suitcase). The 3D files contain each part as an individual object so this makes it possible to manipulate the figure into other positions.
All colors can be modified (9 color groups). The materials file (.mtl) associated with the OBJ file determines the colors for the model.
